I have a 528 crate hemi that runs hot 190-210 degrees while driving. I have installed a 4 core cross flow alum radiator. Plugged the by pass in the water pump, replaced and removed the stat. new hoses, an under drive pulley,and distilled water with Gunk liquid cool and I still run hot, Any one have a suggestion. The factory claims this engine should run around 175-180 deg
